Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy vehicle braking systems, in particular to a braking device for new energy vehicles. BACKGROUND

[0002] With the rapid development of the new energy vehicle industry, the braking device, as one of the core components to ensure driving safety, is facing unprecedented challenges and higher performance requirements. However, under the trend of lightweight design of new energy vehicles, some braking devices sacrifice structural strength in order to reduce weight. Key components such as brake shoes often use single material or simple structure design, and lack effective strengthening measures. In the process of frequent braking, especially in high-speed driving or emergency braking conditions, the braking device bears huge friction force, impact force and vehicle inertia force. Due to insufficient structural strength, the brake shoe is prone to deformation, cracking and even breaking, resulting in brake failure;

[0003] And the braking demand of new energy vehicles is different from that of traditional fuel vehicles, and the existence of the energy recovery system puts higher requirements on the friction characteristics during braking. The selection of friction material and the structure design of the traditional braking device are relatively simple, and the wear resistance is poor. In the process of frequent braking, the wear rate is fast, and it needs to be replaced frequently, which not only increases the use cost, but also affects the overall performance stability and safety of new energy vehicles due to the fluctuation of braking performance.

[0004] The above information disclosed in the background of the application is only used to increase the understanding of the background of the application, and therefore, it can include prior art known to those skilled in the art. CONTENT OF THE INVENTION

[0005] In order to solve the problem that key components such as brake shoes often use single material or simple structure design, and lack effective strengthening measures. In the process of frequent braking, especially in high-speed driving or emergency braking conditions, the braking device bears huge friction force, impact force and vehicle inertia force, the present application provides a braking device for new energy vehicles.

[0006] The braking device for new energy vehicles provided by the present application adopts the following technical scheme:

[0007] A braking device for new energy vehicles, comprising a brake shoe, the inner wall of the brake shoe is fixed with a bottom plate in an integral structure, the outer wall of the brake shoe is fixedly installed with a reinforcing outer plate, the middle part of the outer wall of the reinforcing outer plate is fixedly provided with a reinforcing friction base material, the two sides of the reinforcing friction base material are both installed with a friction lining, and the two ends of the brake shoe are both provided with an opening.

[0008] Preferably, an installation opening for providing component installation space is opened at the center of the inner wall of the brake shoe, bolts are provided inside both sides of the positioning socket, and the positioning socket is connected to the base plate through the bolts.

[0009] Preferably, positioning holes are provided at both ends of the bottom plate, and matching elastic buffer hooks are connected in the positioning holes. A reset spring for support is connected between the two elastic buffer hooks.

[0010] Preferably, a piston is installed at the center of the piston cylinder, and both side output ends of the piston are respectively connected to connectors.

[0011] Preferably, the two connecting heads are fixed to the outer wall of the base plate, and a connecting piece is welded to the middle of the outer wall of the piston cylinder.

[0012] In summary, this application has the following beneficial technical effects:

[0013] This application provides a stable support foundation from the inside through the bottom plate, and strengthens the outer plate from the outside to further enhance its anti-deformation ability, so that the brake shoe can better maintain its own shape and structural integrity, reduce the risk of damage and deformation caused by external forces, ensure the long-term stable and reliable operation of the brake system, and improve driving safety;

[0014] By strengthening the coordination between the friction base material and the friction lining, the enhanced friction base material provides a basic and relatively stable friction force, while the friction lining further increases the friction coefficient between the brake drum (or other brake mating components). The two work together to effectively enhance friction during braking, enabling the vehicle to slow down and stop more quickly and effectively during braking operations. Furthermore, this multi-layer friction structure design allows for flexible adjustment and replacement of the friction lining according to different operating conditions and wear conditions, while maintaining excellent friction performance, thereby extending the service life of the entire brake shoe and reducing maintenance costs.

[0019] The following is combined with Figures 1-3 This application is described in further detail.

[0020] The embodiment of the present application discloses a braking device for new energy vehicles. Figure 1 The brake shoe 1 comprises a brake shoe 1 with an installation opening 6 at the center of its inner wall, providing space for component installation. A base plate 2 is fixed to the inner wall of the brake shoe 1 as an integral structure, while a reinforcing outer plate 3 is fixed to the outer wall of the brake shoe 1. This combined internal and external reinforcement design significantly enhances the overall structural strength of the brake shoe 1. The base plate 2 provides a stable support base from the inside, while the reinforcing outer plate 3 further enhances its deformation resistance from the outside. This allows the brake shoe 1 to better maintain its shape and structural integrity, reducing the risk of damage and deformation caused by external forces, ensuring long-term stable and reliable operation of the braking system, and improving driving safety. A reinforced friction base 5 is fixed to the center of the outer wall of the reinforced outer plate 3. Friction linings 4 are mounted on both sides of the reinforced friction base 5. The reinforced friction base 5 provides a basic and relatively stable friction force, while the friction linings 4 further increase the friction coefficient with the brake drum (or other brake mating components). The two work together to effectively enhance friction during braking, allowing the vehicle to decelerate and stop more quickly and effectively during braking operations.

[0021] like Figure 2 As shown, openings 10 are provided at both ends of the brake shoe 1, and a positioning socket 8 is connected to the opening 10 at one end. Bolts 9 are provided inside the two sides of the positioning socket 8. The positioning socket 8 is connected to the base plate 2 through the bolts 9, which is convenient for connection and positioning with the brake drum (or other brake matching components). During the assembly process of the brake system, precise positioning helps to form a correct matching relationship between the various components, ensure the normal operation of the brake system, and prevent safety hazards such as brake failure caused by poor connection.

[0022] In this application, a piston cylinder 11 is installed in the opening 10 at the other end, and a piston 14 is installed at the center of the piston cylinder 11. The output ends on both sides of the piston 14 are respectively connected to connectors 13. The two connectors 13 are fixed to the outer wall of the base plate 2. A connector 12 is welded to the middle of the outer wall of the piston cylinder 11. When the piston cylinder 11 works to push the piston 14 to move, it can stably transmit power to the base plate 2, thereby driving the entire brake shoe 1 to perform braking action.

[0023] As shown in Figure 3 The two ends of the bottom plate 2 are provided with positioning holes 7, and the positioning holes 7 are connected with matched elastic buffer hooks 16; the two elastic buffer hooks 16 are connected with a reset spring 15 for supporting; during braking, the brake shoe 1 will be subjected to a large impact force, and the buffer structure composed of the reset spring 15 and the elastic buffer hooks 16 can absorb and buffer part of the impact force, so as to avoid that the impact force directly acts on the brake shoe 1 and other connected components, and reduce the possibility that the components are damaged due to instantaneous excessive impact force; meanwhile, after braking, the reset spring 15 can help the brake shoe 1 to return to the initial position, so as to prepare for the next braking, and further improve the stability and durability of the braking system.

[0024] The implementation principle of the brake device for new energy vehicles in the embodiment of the application is as follows:

[0025] In the vehicle braking system, the brake shoe 1 is installed with the brake drum of the new energy vehicle in advance, and the brake shoe 1 is a key braking execution component. The integral structure bottom plate 2 of the inner wall and the reinforced outer plate 3 of the outer wall jointly guarantee the overall structural strength, so that the brake shoe 1 can withstand external force during braking. During braking, the piston 14 in the piston cylinder 11 moves under the driving of liquid pressure and other external forces, and the power is stably transmitted to the bottom plate 2 through the two side connecting heads 13, so as to drive the whole brake shoe 1 to move. The reinforced friction base material 5 of the outer wall of the brake shoe 1 and the friction linings 4 on both sides are in contact with the brake drum (or the corresponding braking matching component), and the vehicle is decelerated and braked by the friction force generated by the cooperation of the two;

[0026] Meanwhile, the two ends of the bottom plate 2 absorb and buffer the impact force generated during braking by means of the elastic buffer hooks 16 and the reset spring 15 therebetween, so as to protect the components from being damaged, and assist the brake shoe 1 to reset after braking, so as to prepare for the next braking, and thus the vehicle braking system can be reliably and stably operated.

[0027] Finally, the following points should be explained: first, in the description of the application, it should be pointed out that, unless otherwise specified and limited, the terms “installation”, “connection” and “connection” should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, and “up”, “down”, “left”, “right” and the like are only used to represent the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;

[0028] Secondly, the embodiment of the utility model discloses only the structure related to the embodiment of the present disclosure, and other structures can refer to the usual design, and the same embodiment and different embodiments of the utility model can be combined with each other under the condition of no conflict;
